Literacy Centers-I'm new at this=)!

I have been teaching Kindergarten for 7 years now. We have always done thematic learning centers in my classroom, but this year, I decided I needed to implement Literacy Centers as well!
After going to workshops and doing lots of research, I have tried several different ways of managing these centers. The 1st couple attempts were a total failure...Live and Learn:) I decided that what worked best for me, was to assign groups to different centers where they had to fill out response sheets. I think the response sheets were nice because they keep the kids on task and holds them accountable for doing their work. I have done LOTS of searches to try to find ideas for literacy centers and have found some pretty cute stuff.  But, THEN I found Kathleen Pedersen's Blog!!!http://growingkinders.blogspot.com She sells her products on teachers pay teachers http://www.teacherspayteachers.com/Store/Kathleen-Pedersen and it is AMAZING stuff! I'm so excited now! These centers are working out great and she has inspired me!!!;)
Here are a couple of the Kathleen's literacy centers that we have been working on the past couple of weeks!

This one is at the working with words center. The kids look at the pic on the 1st bug and build it. Then they change one letter in the word to make another word. (This one is bug to bag)

This one is a popcorn word scramble. They have to unscramble to popcorn word and then write it on their response sheet. LOVE IT!!
Right now, I have 3 of these kind of centers going, while I am doing guided reading with a 4th small group.
Literacy centers are 30 minutes long. So, when the students are finished with their "MUST DO" centers and response sheets, then they can choose a "CAN DO" center to go to.
Here are a few pictures of a couple of the "Can Do" centers that I have available for the kiddos:

The Reading tent is always a big hit! I got this adorable Tree tent from Target!!

Reading the Room!

Making letters and words with different manipulatives. This child has chosen the geoboards to work with.

Various Alphabet, rhyming and words puzzles.
Like I said, Kathleen Pedersen has inspired me and I have found some centers that I LOVE and that work really well in my classroom. But, next week we are starting our rainbow theme! So, I decided to give it a try and create some of my own centers.

Here is the 1st one I've made:) The students will look at the popcorn word on each rainbow and build it using the rainbow colored letters.  They will then write the words that they made on their response sheet using crayola fine tip markers and matching each letter to the color as they write making "Rainbow Words"!  We'll see how it goes on Tuesday...Wish me luck!!!
